More greenhouse space.

I picked up an idea from Vic Aspland (Alpine Garden Soc.
March Journal) who stacks his washed pots upside down vertically on a shelf. This saves floor space, where I kept mine stacked in plastic boxes. I can now save these boxes for something else in the shed.
This led to more thinking about space saving. I have now cut some GCs black plastic plant trays brought home with plants in, with spaces of various sizes, to fit a Gravel tray. This way I can fit more plants into the space, they dont get knocked over, I dont have to use plant saucers, easier to keep a half-inch layer of water in the tray to keep the roots moist.
This has cheered me considerably in this miserable weather.
